What symptoms are commonly associated with Nitrogen Narcosis?

The symptoms associated with nitrogen narcosis can be understood by considering its physiological effects on the body at depth. Nitrogen narcosis occurs when divers descend to depths typically greater than 30 meters (100 feet), where the pressure increases and nitrogen from the breathing gas becomes denser and affects the central nervous system.

Commonly, nitrogen narcosis is likened to the effects of alcohol intoxication because both can impair mental functions and reduce cognitive capabilities. This resemblance includes symptoms such as impaired judgment, euphoria, and decreased motor skills, which can mimic the sensations one experiences under the influence of alcohol. Because of these parallels, divers might describe feeling "intoxicated" due to the alterations in their perception and decision-making abilities caused by nitrogen's effects on the brain.

In contrast, while severe headaches, confusion, hallucinations, and extreme fatigue are symptoms experienced during other diving-related issues or other medical conditions, they do not directly characterize nitrogen narcosis in the same way that the feelings of alcohol intoxication do. Understanding this comparison helps divers recognize the signs of nitrogen narcosis and take necessary precautions while diving.
